MANIFOLD VALVE-LOCK.

Application filed May 11, 1917.

To all whom z'v' may concern:

Be it known that I, ERNEST l. CLARK, a citizen of the United States, residing at Morriston, in the county of Levy and State of Florida, have invented new and useful Improvements in Manifold Valve-Locks, ot' which the following is a spetatication.

. This invention relates to valve locks espe- }c1 ally adapted to be applied to the manifold pipe of an automobile or a similar machine and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide a lock of the character stated which is of simple and durable structure and which includes as an operative clement thereof the shaft of a valve which is located in the manifold pi e in a manner that when the key is inserte in the lock and turned the valve may be swung from an'opcn to a closed position and vice versa.

A prime object of the invention is to provide a simple and etlicient means for pre venting unauthorized persons from using the machine and consequently when the owner of the machine leaves the same he may move the' valve to a closed position and carry the key with him and hence be is reasonably assured that the machine will not be used in his absence.

In the accompanying drawings- Figure 1 is side view of theunanitold pipe of an automobile machine showing the valve lock applied.

Fig. 2 is a sectional view of the lock cut on the line 2-2 of Fig. 1.

Fig. 3 is a section through the manifold of the device cut on the line 33 of Fig. 2.

Fig. 4 is a horizontal sectional view of the lock. 7 I As illustrated in the accon'ipanying drawing the manifold pipe 1 is of usual form and pattern and one end thereof is connected with the earburetcr of the machine while the branches of the said pipe are connected with the engine cylinders in a usual manner. A lock easing 2 is positioned at the side of the pipe 1 at a point just below the inner ends of the branches of the said manifold and the casing 2 is provided with a barrel 3 in which may be located a series of ridges 4. A shaft 5 is journaled in the manifold pipe 1 and one end of the said shaft enters the lock casing 2 and is provided with depres- Specification of Letters Patent.

sions 6 adapted to receive the end portions of a key T when the same is inserted in the barrel 2;? of the lock casing 2. A valve 8 is carried by'the shaft, 1 and may be moved to a position transverse of the pipe 1 whereby the passageway through the said pipe is interrupted or the said valve may be moved to a position at right angles to the passageway through the pipe and hence the explosive mixture may pass through the pipe when the valve. is in an open position.

The casing 2 is secured in position upon the. pipe 1 by means of bolts or rivets t) which pass transversely through the casing and pipe and through a plate 10 mounted at the I inner side of the pipe 1. lackings 11 of asbestos or other suitable material are interposed between the casing 2 and the plate 10 and the pipe 1. One end of the shaft 5 is housed in the barrel 3 and the other end of the said shaft is covered by the plate It), thus sealing the joint where the shaft 5 passes through the sides of the pipe 1. By this arrangement it would be ditlicult for an uiuluthorized person to tamper with the. lock withoutcusing a key to open the valve 8, for it the securing devices 0 are broken or cut they would work or fall out oi their openings in the pipe 1 and thus admit. too much air.

The device may be applied to a manifold pipe by drilling holes through the same, applying the plate It), casing 2 nd the-packings to the. opposite sides thereof, then passing the bolts 1) through the said holes and the said parts and upsetting the ends of the bolts as shown in Fig.2.

lVhen the owner of the machine leaves the same he inserts the key 7 in the barrel 3 and lock casing 2 and the said key is turned shaft 5 is rotated and the. valve 8 is moved to a closed position within the manifold pipe 1. When the owner leaves the ma hi e he carries the key with him and consequently he'is reasonably assured that the machine will not be used in his absence. When it is desired to use, the machine the key 7 is inserted in the barrel 3 and lock casing 2 and is turned whereby the shaft 5 is rotated and the valve 8 is moved from a closed to an open position in the manifold pipe 1 and hence the passageway through the said pipe is opened and the explosive mixture may flow freely through the same.
